DEVICE FOR PREVENTING THE ESCAPE F EFFLUVIA FROM PRlVY-VAULTS ANDIDRAINS.

SPECIFICATION forming part 6f Letters Patent No. 282,437, dated July 31,1888.

Application filed October 2,1882. (No model.)

To all iuhom it may concern:

Be it known that I, HENRY O. BUDDENBERG, of Cincinnati, Hamiltoncounty," Ohio, have invented a new and useful Device for Preventat alltimes, except during use of the privy or urinal, closes the passagebetween the vault'or drain and the dwelling, and which, by the simpleact of occupancy of the privy or urinal,

automatically throws open, for the time being,

the said flap or valve, which latter again automatically closes theinstant .of the disuse of the privy or urinal. In the accompanyingdrawings, Figure 1 is a vertical'section of a privy provided with myinvention, the same being shown in its normal conditionthat is to say,with the flap or valve closed. Figs. 2 and 3 represent theseat withvalve open by sections, respectively, at right angles and parallel tothe seat-front. Fig. 4 is avertic'al section, whichshows, in the closedcondition, a water-closet'provided with my improvement.

Fig. 5 is a section at right angles to the section Fig. 4 of such awater-closet in the open condition. Fig. 6 is a top view of the castingwhich constitutes my valve-seat.

Fig. 7 shows, by vertical section, an application of the same principleto -a urinal.

A may represent a vault or cesspool; B, privy-floor; O, trunk or riser,to which is secured by hingeD the privy-seat E.

r F represents one of two springs that operate to uphold the front edgeof the seat, as shown in Fig. 1. Said seat, when unoccupied, (actingthrough rods G, whose racks H mesh in pinions I upon shaft J of flap orvalve K,) operates to hold said flap to the closed position shown inFig. 1. The same seat, when pressed down by an occupant, operatesthrough the same members to open the flap, and during such occupancy tohold the flap open, as seen in Figs. 2 and 3. I

In Figs. 4 and 5 the same principle is shown 7 applied to awater-closet; In this form the flap and its pinion are so related to theoperating-rack as to act as a lever of the first class, the flap beingopened by an ascending. in-

stead of a descending movement of the rack H, which in this modificationis connected with rod G through the medium of a short le-' ver, L. InFig. 4 the bowl M of the watercloset is of stoneware, and occupies aniron trunk, which constitutes the flap-seat. In Fig. 5 the bowl andtrunk constitute a single casting.

In the form shown in Figs. 1, 2, and 3 journal-bearings N of shaft J arefastened to the under side of the floor B. In the form shown in Figs. 4,5, and 6 the shaft J is journaled in sockets that constitute castprojections p from the walls of a cast chamber, 1?.

Q shows a hydrant service-pipe communicating with a valve or cock, R,whose stein S, being depressed bydescent of the privyseat, permits waterto discharge under deflector T and flush the bowl during the occupancyof the privy-seat.

I claim as new and of my invention- -1. The combination, with thehopperor soilpipe of a water-closet, privy, or urinal, of a flap orvalve, K,adapted to be operated automatically by the weight of an occupantthrough the medium of pinion I, rack H, and suitablyinterposed levers,substantially as and for the purpose set forth.

2. The combination of spring-seat E D, rods G S, rack H, pinion I, flapK, lever L, bowl M, and flush-cock It, substantially as and for thepurpose set forth.

In testimony of which invention I hereunto set my hand. i

HENRY O. BUDDENBERG.
